iTurbo vs FlareFinder
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
iTurbo
This app simulates fluid dynamics by solving Navier-Stokes equations for 2D incompressible turbulence. It uses a direct numerical simulation method with Euler time stepping and Fourier space calculations for efficiency.
- Direct Numerical Simulation (DNS)
- Navier-Stokes equation solver
- 2D incompressible turbulence
- Euler time stepping
- Fourier space calculations
- Vorticity field transformation

This application performs a Direct Numerical Simulation (DNS) where the Navier-Stokes equations are solved for two dimensional incompressible homogeneous turbulence. These equations are a set of nonlinear partial differential equations. The time stepping is performed with a simple Euler method where the time step is calculated so that the CFL number does not exceeds the given number (should be less than 0.8 otherwise the simulation blows up). The equations are solved in the Fourier space where the calculation of the nonlinear term transforms to a simple multiplication. The main CPU usage is consumed by transforming the vorticity field back and fourth between the Normal space where the time-stepping is performed and the Fourier space where the nonlinear term is calculated.

Verdict
The clearest difference is rating: iTurbo at 5.0 against FlareFinder's 2.1. FlareFinder's advantage is ratings volume (28 vs 1) and iOS requirement (7.0 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
iTurbo holds the better App Store score, 5.0 against 2.1. That said, the two scores are not equally well evidenced: FlareFinder has 28 ratings behind it against 1, so its average is the more settled of the two.
